Constraints on stellar parameters of the SPB star HD182255 from complex asteroseismology

TL;DR

This paper uses complex asteroseismology to constrain stellar parameters of the SPB star HD182255, testing models of opacity, composition, and overshooting through seismic data and the nonadiabatic parameter $f$.

Contribution

It introduces a combined seismic approach using frequencies and the $f$ parameter to test stellar physics models for HD182255.

Findings

Strong constraints on radial modes of HD182255

Empirical $f$ values derived for dominant modes

Tests of opacity, composition, and overshooting models

Abstract

Seismic modeling of the Slowly Pulsating B-type star HD182255 yields strong constraints on the radial orders of the two dominant modes. For these frequencies, we derive also the empirical values of the complex nonadiabatic parameter $f$. These two seismic tools, i.e., pulsational frequencies and the associated values of $f$, allow to test available opacity data, chemical composition and overshooting efficiency.
